Comment # 55 on bug 73338 from Chernovsky Oleg

I'm digging deeper...

> #define		FDO_PWM_MODE_MASK			(3 << 11)

aaaand....

> #define FDO_PWM_MODE_STATIC  1
> #define FDO_PWM_MODE_STATIC_RPM 5

and in ci_fan_ctrl_set_static_mode we're taking one of these modes as argument
and shifting it, I assume? But how can 5 (0b101) match into mask 3 (0b11)?
